Application filed December 9, 1904. Serial No. 236,158.

T 0 all whom it may concern:

Be it known that I, JOHN B. HADAWAY, a citizen of the United States,residing at Brockton, in the county of Plymouth and State ofMassachusetts, have invented certain new and useful Improvements inImpression or Imitation Stitch Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the in vention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to impression or imitation stitch machineswhich are used in the manufacture of boots and shoes to form ornamentalindentations upon the upper surface of the projecting edge of the sole.

Impression or imitation stitch machines usually comprise a rotaryindenting wheel provided with teeth so shaped and spaced as to producethe desired form of indenta tion when the edge of the shoe sole ispassed beneath the wheel. In machines of this class as heretoforeconstructed a guard has usually been provided for preventing the shoeupper from coming in contact with and being marred by the end of theindenting'wheel. This guard has consisted of a thin plate so located asto extend across the end of the wheel between the wheel and the shoeupper. The provision of this guard plate has been found to beobjectionable, as the plate holds the shoe away from the wheel andprevents the shoe from being manipulated so as to cause the teeth of'thewheel to extend into the crease between the upper and the projectingedge of the shoe sole. The interference of this guard plate with theproper manipulation of the shoe is especially noticeable while the edgeof the sole at the toe portion of the shoe is being indented. At thisportion of the shoe the upper bulges out over the surface of the sole toa noticeable degree, and in order to cause the indentations to extend asfar as possible into the crease between the upper and sole, the operatoroften presses the shoe against the guard plate with sufficient force tobend or break the plate or to mar the shoe upper. In case no guard plateis provided great care is required on the part of the operator while thetoe portion of the sole edge is being acted upon to cause theindentations to be properly located and at the same time prevent theupper from coming in contactwith and being injured by the end of theindenting wheel.

The object of the present invention is to provide an indenting wheelwhich will allow the shoe to be manipulated so as to cause the teeth ofthe tool to extend into the crease between the upper and the projectingedge of the sole without liability of injury to the upper by contactwith the end of the wheel.

Another object of the invention is to provlde an impression or imitationstitch machine with a guard for the upper which will guide the shoe andat the same time permitthe upper to be brought close to the end of theindenting wheel.

With these objects in view, the present invention consists in theimproved form of indenting wheel and in the improved guard for guidingthe shoe and holding the upper out of contact with the indenting wheelhereinafter described and claimed.

The several features of the present invention will be clearly understoodfrom an inspection of the accompanying drawings, in which- Figure l is aview in side elevation of a portion of an impression or imitation stitchmachine embodying the same in their preferred form, the guard for theupper being broken away, the indenting wheel being shown in section, andthe toe portion of a shoe being shown in position to be acted upon bythe indenting wheel; Fig. 2 is a plan View partly in section of theparts illustrated in Fig. 1, and Fig. 3 is an end view of the indentingwheel and guard, showing the projecting edge of the shoe sole in crosssection.

1 indicates an indenting wheel which is frusto-conical in shape, as isusual in this class of machines, and which is provided upon itsperiphery with teeth shaped and spaced to produce the desired form ofindentation. This wheel is mounted upon the outer end of a shaft 2 withits larger end extending beyond the end of the shaft. The shaft 2 isjournaled in a bearing 3, and is secured to the shaft by means of aheaded screw 4 screwing into the end of the shaft.

5 indicates the work support upon which the tread surface of the shoesole is supported during the indenting operation, and

6 indicates a guard arranged to engage the shoe upper and prevent theupper from coming in contact with the indenting wheel.

In accordance with the present invention, a recess 7 is provided in theend of the i11- denting wheel, as is clearly shown in Fig. 1. Thisrecess provides a space into which the bulging portion of the upper atthe toe portion of the shoe can project without coming into contact withthe end of the indenting wheel or the head of the screw 4, so that whenthe toe portion of the shoe is being operated upon the shoe can bepressed toward the wheel to cause the teeth of the wheel to extend intothe crease between the upper and the projecting edge of the sole.Preferably the periphery of the wheel is beveled off at its outer edgeas indicated in Figs. 1 and 2 so that the outer edge of the wheel issmooth and will not mar the upper if brought accidentally intoengagement therewith. Also preferably the recess flares outwardly towardthe periphery of the outer end of the wheel to allow the teeth of thewheel to more readily extend into the crease between the upper and thesole. The surface of the recess is smooth and if desired the shoe can beforced toward the wheel until the upper contacts with the surface of therecess as indicated in Fig. 1, and the portion of the wheel whichextends into the crease between the upper and the sole forms a guide forthe shoe. Also, in accordance with the present invention the guard 6 isarranged to bear against the shoe upper at one side of the indentingwheel as indicated in Figs. 2 and 3, the surface of the guide whichcontacts with the shoe upper being located substantially flush with theend of the indenting wheel or slightly beyond the end of the wheel. Asillustrated, the guard extends circumferentially about the indentingwheel, and no portion of the guard extends into a position to contactwith the upper in front of the indenting wheel and prevent the upperfrom being brought close to the end of the wheel. To provide means foradjusting the guard so as to cause its upper engaging surface to projectmore or less beyond the end of the indenting wheel,

the guard is secured to a stationary portion 8 of the machine frame bymeans of a bolt 9 passing through a slot in the frame and screwing intothe rear portion of the guard.

It is preferred to use the improved form of guard above described withthe improved form of indenting wheel, as when these parts are usedtogether the shoe can be accurately guided to cause the teeth of theindenting wheel to extend into the crease between the upper and theprojecting edge of the sole without any liability of injuring the upper.

It will be evident however that the guard can be used advantageously inconnection with the usual form of indenting wheel, which is not providedat its end with a recess to receive the bulging portion of the upper.

The invention having been thus described, what is claimed is I 1. Amachine for making impression or imitation stitches, having, incombination, a shaft, a frusto-conical indenting wheel mounted thereonwith its larger end extending beyond the outer end of the shaft, and'aguard having a surface substantially flush with the larger end of theindenting wheel mounted to bear against the shoe upper at one side ofthe indenting wheel and guide the shoe while permitting the upper to bebrought close to the end of the indenting wheel, substantially asdescribed.

2. A machine for making impression or imitation stitches, having, incombination, a shaft, a frusto-conical indenting wheel mounted thereonwith its larger end extending beyond the outer end of the shaft, saidindenting wheel being provided at its larger end with a recess toreceive the bulging portion of the upper at the toe of the shoe, and aguard arranged to bear against the upper at one side of the indentingwheel, substantially as described.

In testimony whereof I afliX my signature, in presence of two witnesses.

JOHN B. HADAWAY.
